IMPROVEMENT INA GAS-REGULATORS.

Specification forming part of Letters Patent No. 2 19,989, datedSeptember 23, 1.879; application filed April 29, 1879.

To all whom it may concern:

Be it known that l', NATHANIEL SLEEMAN, of Birmingham, in the county ofNew Haven and State of Connecticut, have inventedfa new and usefulGovernor Gas-Burner, of which the following is a specificationY iFigures l and'3 represent vertical sections, respectively, of a streetand house gas-regulating burner. Fig. 2 is a cross-section' of cam N.

Similar letters of reference indicate corre,- sponding parts.

The object of this invention is to furnish a gas-burner provided with agovernor for regulating and cutting off the'liow of gas.

This device is especially applicable to street lights or lamps, for byits use all the lights of a city may be almost simultaneously jextinguished by simply removing for a few minutes the pressure of thegas at the gas-works.

A is a casing, preferably made cup-shaped, with a tube, B, passing upthrough its center and projecting slightly below its bottom, where thediameter of thevbore of the tube is veryconsiderably contracted by aValve-seat tube, L, the lower end of which oii'ers a seat for the valve.Extending up through this valve-seat tube is a valve-rod, C, carrying onits lower end, and below the valve-seat tube, the valve D, whichconsists of a long round plug of metal swelling at the center andtapering to each end. To the upper end of this valve-rod is fastened thecross-bar E, that extends across the upward central tubular extensioncof-of the iloat F, and is soldered or otherwise ,fastened to the topofthe ioat. The top of the iloat resembles a circular disk slightlyelevated at the center, where it surrounds the central tubularextension, and slopes downf ward to its edge, to which is solderedorotherwise fastened. the broad conical ring that prov jects downwardand forms the sides of the oat. In the top of the tubular extension a.is inserted a bushing, b', projecting upward, into which the split screwor check G is set, which can be adjusted to regulate the ow of gas tothe burner. The tube or burner H, having in its smaller end the tip I,is screwed on the Abushing b', so as to inelose the split screw or checkG. The cap or cover K of the device, with its central and upwardprojecting tube, is then set in position, as shown in the drawings.Screwed onto the valve-seat tube L is the connecting-pipe M, having anenlarged transverse chamber, through which the cam N is inserted, andheld by nut d. The upper wall of this chamber is pierced with a hole,f', for the upward flow of gas, and affords a seat for the valve as itis moved downward, while the lower wall of the chamber is provided witha hole, g', for the admission of gas from the street-pipes. The tloat issuspended in glycerine contained in the case or shell A. The course ofgas entering the connecting-pipe is through the hole g into thetransverse chamber, and thence through the hole f', valve-seat tube L,tube B, bushing bj, split screw G, and burner H tothe tip I.

Should the pressure from the main increase above the desired point, theiloat will be lifted and draw up with it the valve D into the uppervalve-seat, so as to limit the ow of the gas and relieve the excessivepressure within the device. On cessation of the pressure the fioat willfall again, and the gas-port through the upper valve seat becorrespondingly opened. Should the pressure at any time be insufficientto keep the lioat raised at all, the valve will fall and close the portin the lower valve-seat, as shown in Fig. l, unless the cam N be turnedso that its edge -shall come in contact with the valve and hold it up.Thus it will be seen that the valve can be adjusted and theports keptopen for the passage of gas to the burners when the gas-pressure isreduced to a minimum. V

The llow of gas to the burner may also be regulated by turning the splitscrew or check G up or down, so as to increase or diminish its sideopenings.

In Fig. 3 the governor gas-burner is shown without thecam and itsnecessary attachments. The valve also is of dicrent shapeffrom thatshown in Fig. l, because of the absence of the cam and its chamber; butin other respects the devices and their operations are identical. Thisburner shown in Fig. 3, being, designed more especially for use inhouses containing gas-meters, does not require all the governing devicesthat it does when applied to streetlamps.

I am aware thaty there are man ydeviees for regulating the flow of gasthrough pipes that are designed to control the supply and pressure oftwo or ymore burners at one andy the same time; but I am not aware thata burner f attached directly to an elcient governor or regulator hasever before been'd'evised. f

It will be observed that both economy in space and simplicity of partsare gained by arranging all the gas-ports and passages per-ypendicularly one above the other.

Having thus described my invention, I claim as new and desire to secureby Letters Patentt 1. The within-described governor gas-burner, iconsisting of thecase A, tube B, valve-rod O,
